PREFLAME REACTIONS IN THE AUTODECOMPOSITION OF ACETYLENIC COMPOUNDS
Abstract
The autodecomposition reactions of compounds such as dipropargyl ether and 1,6-heptadiyne have been studied by examination of the high-pressure autodecomposition flame and by analysis of the products of the low-pressure pyrolysis of these and related compounds. The gaseous products of pyrolysis at 900 C. indicate the splitting of the long-chain molecules into two smaller molecules by a homogeneous gas-phase reaction proceeding by way of a cyclic intermediate and involving an internal proton shift and displacement. At this pyrolysis temperature polymerization also occurs to a considerable extent (about 50%) and homolytic cleavages to a slight extent (about 1-2%). Evidence was also found that the unimolecular cleavage either precedes or occurs concurrently with the high-pressure autodecomposition reaction. (Author)
